What is "sumantri"

Sumantri (also spelled Soemantri or Soemantri Brodjonegoro) is a sharp mountain in the western Sudirman Range ( New Guinea), it rises .

The peak is approximately 2 km northeast of Carstensz Pyramid (4,884 m), the highest mountain of Oceania. The north side of Sumantri is dominated by tremendous cliffs, part of the Noordwand (North wall) of the Carstensz Massif, that wrap around onto both the eastern and western sides of the mountain. Remnants of the once mighty North Wall Firn still cling tenuously to the southern aspects of the peak. It is unlikely that this ice will last for more than the next fifteen years.
